Interlink Hybrid DC Circuit Breaker [PDF]
IEEE Transactions on Industrial Electronics, 2018 —To protect HVDC grids from DC faults, the concept of a hybrid DC circuit breaker is widely accepted due to its low conduction losses and fast interruption speed. For a well-built DC grid, a massive number of hybrid DC circuit breakers have to be installed. This will lead to high capital costs.

Superconducting Interface for a DC Circuit Breaker [PDF]
8th IET International Conference on Power Electronics, Machines and Drives (PEMD 2016), 2016 High voltage direct current (HVDC) circuit breakers are a key technology to enable fault management for multi terminal DC (MTDC) networks. DC circuit breakers using superconductors for current limiting have been proposed previously and experimentally tested at low voltage levels.
